FIELD OF THE INVENTION

The present invention provides novel aryl dihydropyridinone andpiperidinone compounds, and their analogues thereof, which are MGAT2inhibitors, compositions containing them, and methods of using them, forexample, for the treatment or prophylaxis of diabetes, obesity,dyslipidemia and related conditions.

BACKGROUND OF THE INVENTION

The prevalence of obesity and diabetes is increasing at an alarmingrate. According to WHO, in 2008, 70% of the U.S. adult population wasoverweight, and among them 33% were obese. Parallel to the explosivenumber of people becoming overweight and obese, in 2008, it wasestimated that 12.3% of the U.S. population had elevated blood glucose[http://www.who.int/diabetes/facts/en/]. The obesity/diabetes epidemicis not unique to the U.S. According to WHO (Fact Sheet No. 312,September 2012), 347 million people worldwide have diabetes. Treatingobesity and improving glycemic control effectively and safely remainmajor challenges for modern medicine.

Monoacylglycerol acyltransferase 2 (MGAT2) has emerged as an attractivetarget for the treatment of obesity and type II diabetes [Yen, C. L. etal., Nat. Med., 15(4):442-446 (2009)]. MGAT2 is highly and selectivelyexpressed in the small intestine where it exerts a pivotal role in themonoacylglycerol-pathway for the absorption of dietary fat. When dietaryfat is ingested, pancreatic lipase digests triglycerides into free fattyacids and 2-monoacylglycerol, which are absorbed by intestinalepithelial enterocytes. Once inside enterocytes, free fatty acids and2-monoacylglycerol are used as building blocks to resynthesizetriglycerides by two sequential acylation steps; first by MGAT and thenby DGAT enzyme reactions. Triglycerides are then incorporated intochylomicrons and secreted into lymph to be utilized as an energy supplyfor the body. MGAT2 knockout mice exhibit a healthy metabolic phenotypeand show resistance to high-fat diet induced obesity, improvement ininsulin sensitivity and decreased fat accumulation in liver and adiposetissue. In addition, genetic deletion of MGAT2 produces mice withincreased levels of GLP1 [Yen, C. L. et al., Nat. Med., 15(4):442-446(2009)]. Taken together, these data show that MGAT2 inhibitors holdpromise to treat metabolic disorders such as obesity, type II diabetesand dyslipidemia.

The term “counter ion” is used to represent a negatively charged speciessuch as chloride, bromide, hydroxide, acetate, and sulfate or apositively charged species such as sodium (Na+), potassium (K+),ammonium (R_(n)NH_(m)+ where n=0-4 and m=0-4) and the like.

When a dotted ring is used within a ring structure, this indicates thatthe ring structure may be saturated, partially saturated or unsaturated.

As used herein, the term “amine protecting group” means any group knownin the art of organic synthesis for the protection of amine groups whichis stable to an ester reducing agent, a disubstituted hydrazine, R4-Mand R7-M, a nucleophile, a hydrazine reducing agent, an activator, astrong base, a hindered amine base and a cyclizing agent. Such amineprotecting groups fitting these criteria include those listed in Wuts,P. G. M. and Greene, T. W. Protecting Groups in Organic Synthesis, 4thEdition, Wiley (2007) and The Peptides Analysis, Synthesis, Biology,Vol. 3, Academic Press, New York (1981), the disclosure of which ishereby incorporated by reference. Examples of amine protecting groupsinclude, but are not limited to, the following: (1) acyl types such asformyl, trifluoroacetyl, phthalyl, and p-toluenesulfonyl; (2) aromaticcarbamate types such as benzyloxycarbonyl (Cbz) and substitutedbenzyloxycarbonyls, 1-(p-biphenyl)-1-methylethoxycarbonyl, and9-fluorenylmethyloxycarbonyl (Fmoc); (3) aliphatic carbamate types suchas tert-butyloxycarbonyl (Boc), ethoxycarbonyl,diisopropylmethoxycarbonyl, and allyloxycarbonyl; (4) cyclic alkylcarbamate types such as cyclopentyloxycarbonyl and adamantyloxycarbonyl;(5) alkyl types such as triphenylmethyl and benzyl; (6) trialkylsilanesuch as trimethylsilane; (7) thiol containing types such asphenylthiocarbonyl and dithiasuccinoyl; and (8) alkyl types such astriphenylmethyl, methyl, and benzyl; and substituted alkyl types such as2,2,2-trichloroethyl, 2-phenylethyl, and t-butyl; and trialkylsilanetypes such as trimethylsilane.

As referred to herein, the term “substituted” means that at least onehydrogen atom is replaced with a non-hydrogen group, provided thatnormal valencies are maintained and that the substitution results in astable compound. Ring double bonds, as used herein, are double bondsthat are formed between two adjacent ring atoms (e.g., C═C, C═N, orN═N).

In cases wherein there are nitrogen atoms (e.g., amines) on compounds ofthe present invention, these may be converted to N-oxides by treatmentwith an oxidizing agent (e.g., mCPBA and/or hydrogen peroxides) toafford other compounds of this invention. Thus, shown and claimednitrogen atoms are considered to cover both the shown nitrogen and itsN-oxide (NO) derivative.

When any variable occurs more than one time in any constituent orformula for a compound, its definition at each occurrence is independentof its definition at every other occurrence. Thus, for example, if agroup is shown to be substituted with 0-3 R, then said group mayoptionally be substituted with up to three R groups, and at eachoccurrence R is selected independently from the definition of R.

When a bond to a substituent is shown to cross a bond connecting twoatoms in a ring, then such substituent may be bonded to any atom on thering. When a substituent is listed without indicating the atom in whichsuch substituent is bonded to the rest of the compound of a givenformula, then such substituent may be bonded via any atom in suchsubstituent.

Combinations of substituents and/or variables are permissible only ifsuch combinations result in stable compounds.

The phrase “pharmaceutically acceptable” is employed herein to refer tothose compounds, materials, compositions, and/or dosage forms that are,within the scope of sound medical judgment, suitable for use in contactwith the tissues of human beings and animals without excessive toxicity,irritation, allergic response, and/or other problem or complication,commensurate with a reasonable benefit/risk ratio.

As used herein, “pharmaceutically acceptable salts” refer to derivativesof the disclosed compounds wherein the parent compound is modified bymaking acid or base salts thereof. Examples of pharmaceuticallyacceptable salts include, but are not limited to, mineral or organicacid salts of basic groups such as amines; and alkali or organic saltsof acidic groups such as carboxylic acids. The pharmaceuticallyacceptable salts include the conventional non-toxic salts or thequaternary ammonium salts of the parent compound formed, for example,from non-toxic inorganic or organic acids. For example, suchconventional non-toxic salts include those derived from inorganic acidssuch as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, andnitric; and the salts prepared from organic acids such as acetic,propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric,ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic,benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric,toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, andisethionic, and the like.

The pharmaceutically acceptable salts of the present invention can besynthesized from the parent compound that contains a basic or acidicmoiety by conventional chemical methods. Generally, such salts can beprepared by reacting the free acid or base forms of these compounds witha stoichiometric amount of the appropriate base or acid in water or inan organic solvent, or in a mixture of the two; generally, nonaqueousmedia like ether, ethyl acetate, ethanol, isopropanol, or acetonitrileare preferred.

For example, compounds of Formula (II), where R³═R⁴═H and R⁶═CN, can bemade according to Scheme 1. Ketones 1 and 2 and 2-cyanoethyl acetate (3)are heated to between 80° C. and 110° C. with ammonium acetate in asolvent such as DMF or DMSO. Ketones 1 and 2 may be different or thesame.

Alternatively, compounds of Formula (II), where R³═R⁴═H, may be madeaccording to Scheme 2. α-Bromoketone 4 is combined withtriphenylphosphine in a solvent such as THF, CH₂Cl₂ or 1,4-dioxane attemperatures between room temperature and reflux. The intermediatetriphenylphosphonium bromide is treated with base, such as NaOH, in asolvent such as methanol and water to form the phosphorous ylide 5. Thephosphorous ylide 5 is heated to 80° C. with ketone 2 in a suitablesolvent such as THF or DMSO to give α,β-unsat'd ketone 6, which mayexist as a mixture of E/Z isomers. Microwave irradiation may be employedto shorten the reaction time. α,β-Unsat'd ketone 6 is treated withconcentrated aq NH₄OH in a solvent such as DMSO in a sealed vessel toprovide amine 7. Alternatively, alkene 6 may be treated with NH₃ in asolvent such as DMSO or DMSO and methanol in a sealed vessel to provideamine 7 Amine 7 is couple with carboxylic acid 8 using a variety ofamide bond forming reactions. For example, carboxylic acid 8 may beconverted to the corresponding acid chloride using oxalyl chloride in asolvent such as CH₂Cl₂ and catalytic DMF. Alternatively, when R⁶ is anamide or a heterocycle, the carboxylic acid 8 may be activated usingtriphenylphosphine and trichloroacetonitrile in a suitable solvent suchas CH₂Cl₂. The acid chlorides thus formed are combined with amine 7 in asuitable solvent such as CH₂Cl₂ or CH₂Cl₂ and DMF in the presence of abase, preferably pyridine. When R² is CF₃, cyclization of amide 9 to acompound of Formula (I) typically occurs during the work-up procedurefor amide 9; for example, when an EtOAc solution of amide 9 is washedwith sat'd aq NaHCO₃. When cyclization does not occur under theseconditions, cyclization may be affected by stirring amide 9 in thepresence of a weak base such as piperidine in a suitable solvent such asEtOH at a temperature between room temperature and reflux.

An alternate synthesis to α,β-unsaturated ketone 6, where R¹ is—(CH₂)_(m)— (phenyl substituted with 0-3 R^(b)) and m=0, is shown inScheme 3. Aryl bromide 10 and α,β-unsat'd ester 11 are coupled usingpalladium (II) acetate, tetrabutylammonium chloride anddicyclohexylamine in DMA at 110° C. α,β-Unsat'd ester 12 is combinedwith O,N-dimethylhydroxyl-amine 13 in the presence of a strong base suchas iso-propylmagnesium bromide in an aprotic solvent such as THF.α,β-Unsat'd amide 14 is combined with aryl magnesium halide 15 toprovide α,β-unsat'd ketone 6. The identity of the halide in the arylmagnesium halide is dependent upon availability of the aryl halide usedto make the Grignard reagent; typically the halide is chloride orbromide.

Non-commercial α,α,α-trifluoroketones 2, where R²═CF₃, may be made fromthe corresponding aldehyde 16 as shown in Scheme 4. Aldehyde 16 isreacted with trimethyl-(trifluoromethyl)silane in the presence of afluoride source, for example cesium fluoride, using a suitable solventsuch dimethoxyethane at room temperature. Other fluoride sources, suchas potassium hydrogen fluoride or tetrabutylammoniumdifluorotriphenylsilicate, and other solvents, such as THF oracetonitrile and methanol, may also be employed. Trifluoromethyl alcohol17 is oxidized using, for example, Dess-Martin periodinane in a suitablesolvent such as CH₂Cl₂.

Ketones of formula 2 may be made according to Scheme 5. For example,aryl halide 18, where X=bromine and the aryl group is a suitablechemical moiety to form a Grignard reagent, is combined with magnesiummetal in the presence of an initiator such as iodine in a suitablesolvent such as THF. Other alkyl halides having a chemical moietysuitable for formation of Grignard reagents, other halides such aschlorine or iodine, other solvents such as diethyl ether or 1,4-dioxane,and other initiators such as 1,2-dibromoethene, may be employed asdetermined by one skilled in the art.

Compound 21 is heated with boronic acid 22, where R═H, in thepresence of a palladium catalyst and base using a suitable solvent suchas 1,4-dioxane, toluene, DMF with or without water. Boronic acid 22 maybe substituted with alternative boronic acid analogs such as boronateesters, trifluoroborates, and others known to those skilled in the art.Palladium catalyst commonly employed include, but are not restricted to,Pd(PPh₃)₄ and PdCl₂(dppf). Other palladium catalyst known to thoseskilled in the art may be employed. Bases commonly employed include, butare not restricted to, K₃PO₄ and K₂CO₃. Other bases known to thoseskilled in the art may also be employed. When n=m=0 and t=1 when X═O orNH, biarylethers or biarylamines such as 23 can be obtained from 21 whenG=OH. Alternatively, biaryl ethers and amines can also be obtained from21, when G=boronic acid or equivalent, via metal-catalyzed coupling withsuitable phenols or amines

Bromide 24 is treated withtris(dibenzylideneacetone)palladium (0) in the presence ofbis(1,1-dimethylethyl)[2′,4′,6′-tris(1-methylethyl)[1,1′-biphenyl]-2-yl]-phosphine(t-butyl-Xphos) using 1,4-dioxane and water as solvent and KOH as base.Phenol 25 and alcohol 26 were stirred in the presence oftriphenylphosphine and DIAD in a suitable solvent such as CH₂Cl₂.

Carboxylic acid 8, where R⁶═CONHR^(c), may be made according to Scheme8. The mono-ester of malonic acid 28, where PG=benzyl group, and amine29 are coupled together using standard amide bond forming conditions.For example, treatment of carboxylic acid 28 with oxalyl chloride inCH₂Cl₂ and DMF provides the acid chloride. The acid chloride is thencombined with amine 29 in the presence of pyridine in a suitable solventsuch as CH₂Cl₂. Other amide bond forming reaction known to those skilledin the art may be employed. The benzyl group is removed using acombination of hydrogen gas and 10% palladium on carbon in a suitablesolvent such as methanol or methanol and EtOAc. Other PG moieties andmethods for their removal known to those skilled in the art may beemployed.

Compounds of Formula (I), where R³ and R⁴ are combined with the carbonatom to which they are attached to form a 3-6 membered carbocycle, orR³═R⁴=F, may be made according to Scheme 9. For example, to synthesizecompounds for Formula (I) where R³ and R⁴ are combined with the carbonatom to which they are attached to form a 3-membered ring (i.e.,cyclopropyl), β-ketoester 30 is stirred at room temperature with1,2-dibromoethane in the presence of a base, for example K₂CO₃, in asuitable solvent such as DMF to provide the cyclopropyl β-ketoester 31.Cyclopropyl β-ketoester 31 is stirred with a suitable amine, such asbenzyl amine, in the presence of a suitable Lewis acid, such as TiCl₄,in a solvent such as CH₂Cl₂ starting at 0° C. then warming to roomtemperature. Other amines, Lewis acids, solvents and temperatures may beused as determined by those skilled in the art. The use of benzylamineprovides imine 32, where PG=benzyl Imine 32 is alkylated with, forexample, trimethyl(trifluoromethyl)silane in the presence of a fluoridesource such as potassium hydrogen fluoride and TFA, using acetonitrileand DMF. Other fluoride sources, such as tetrabutylammoniumdifluorotriphenylsilicate or cesium fluoride, other acids such as HOAcor HCl, and other solvents may be employed as determined by thoseskilled in the art. Use of trimethyl(trifluoromethyl)silane providesamino ester 33, where R²═CF₃. Ester hydrolysis of amino ester 33 wasdone in the presence of lithium iodide in refluxing pyridine to provideamino acid 34. Use of other hydrolysis conditions known to those skilledin the art may be employed. Cyclization of amino acid 34 to β-lactam 35was affected by activating the carboxylic acid of amino acid 34 withoxalyl chloride in a suitable solvent such as CH₂Cl₂ containingcatalytic DMF. The cyclization occurred spontaneously at roomtemperature to provide β-lactam 35. Other methods for activating thecarboxylic acid may be employed as determined by those skilled in theart. β-Lactam 35 is arylated using an organometallic reagent.Organometallic reagents may include, for example, Grignard reagents ororganolithium reagents, formed from a suitably substituted phenyl ringcontaining a halide atom able to react with either elemental magnesiumto form a Grignard reagent or with an alkyl lithium reagent to form anphenyl lithium reagent via transmetallation. Exact conditions requiredto form these phenyl organometallic species must determined by thoseskilled in the art. A suitable aprotic solvent is used, for example,THF. Other suitable solvents may be employed as determined by thoseskilled in the art. The reaction is carried out between room temperatureand reflux depending upon the identity of the organometallic reagentemployed and the substitution pattern on β-lactam 35. The β-amino ketone37 thus formed is deprotected using hydrogen gas and 10% palladium oncarbon in a suitable solvent such as methanol containing 4.4% formicacid to provide β-amino ketone 38.

Other conditions to remove the benzyl group may be employed asdetermined by those skilled in the art. β-Amino ketone 38 is acylatedwith carboxylic acid 8 using conditions described in Scheme 2 to givethe β-keto amide 39.

Thus, a compound of Formula (I), where x is asingle bond and R⁶═CN, was heated to 80° C. in the presence of afluorinating reagent,1-fluoro-4-hydroxy-1,4-diazoniabicyclo[2,2,2]octanebis(tetrafluoroborate), in a suitable solvent such as DMF in thepresence of a base such as Na₂CO₃ to provide compounds of Formula (I),where y is a single bond, R⁵═F and R⁶═CN. Other fluorinating reagents,solvents and bases may be employed as determined by one skilled in theart.

Compounds of Formula (I), where x and y are both single bonds and R⁵═H,can be made according to Scheme 11. Reduction of compounds of Formula(I), where x equals a single bond and y equals a double bond, is carriedout using a suitable catalyst such as palladium on carbon under anatmosphere of hydrogen gas at suitable pressure, such as 50 psi, toeffect reduction of the double bond y to a single bond.

Other Lewis acids, solvents and temperatures may beused as determined by those skilled in the art. Imine 40 is alkylatedwith ketone 1 in the presence of a base, such as LiHMDS, KHMDS, NaHMDS,or LDA in an aprotic solvent such as THF or ether at a temperatureranging from −78° C. to ambient to provide β-amino ketone 41 as amixture of two diastereomers, which can be separated by silica gelchromatography to give the desired isomer 42. Other metal enolates (suchas titanium enolate), solvents, and temperatures may be used asdetermined by those skilled in the art (T. P. Tang, J. A Ellman, J. Org.Chem. 1999, 64, 12-13, J. Org. Chem. 2002, 67, 7819-7832). Preferably,chiral S— or R-2-methylpropane-2-sulfinamide can be optionally used togenerate each of the optically pure enantiomers of imine 40 that canallow for chiral induction to prepare diastereomerically enriched ketone42. In these cases, the product mixture can be further purified bysilica gel chromatography to obtain desired products with diaseteromericexcess of >97%. β-amino ketone 42 thus formed is deprotected using HClin a suitable solvent such as MeOH to provide β-amino ketone 43. Otherconditions to remove the t-butylsulfinyl group may be employed asdetermined by those skilled in the art. β-Amino ketone 43 is acylatedwith carboxylic acid 8 using conditions described in Scheme 2 to givethe β-keto amide 44. Stirring β-keto amide 44 with a base such as sodiumethoxide in a suitable solvent such as ethanol at room temperatureprovides compounds having Formula (II).

Alternatively, compounds of Formula (II), where R³═R⁴═H, may be madeaccording to Scheme 13. Ketone 2 can be reacted with2-methylpropane-2-sulfinamide in the presence of a suitable Lewis acid,such as Ti(OEt)₄, in a solvent such as THF at a temperature ranging fromambient to reflux to provide imine 45. Other Lewis acids, solvents andtemperatures may be used as determined by those skilled in the art.Imine 45 is alkylated with the enolate of an ester in a suitable aproticsolvent such as THF or ether starting at −78° C. then warming to 0° C.or room temperature to provide protected β-amino ketone 46 as a mixtureof two diastereomers, which can be separated by silica gelchromatography to give each individual chiral compound. The generationof the ester enolate is achieved by treating the ester, such as methylacetate, with a suitable base such as LHMDS, KHMDS, NaHMDS, or LDA in anaprotic solvent such as THF or ether at a temperature ranging from −78°C. to ambient. Other metal enolates (such as titanium enolate),solvents, and temperatures may be used as determined by those skilled inthe art (T. P. Tang, J. A Ellman, J. Org. Chem. 1999, 64, 12-13, J. Org.Chem. 2002, 67, 7819-7832). Preferably, chiral S- orR-2-methylpropane-2-sulfinamide can be optionally used to generate eachof the optically pure enantiomers of imine 45 that can allow for chiralinduction to prepare diastereomerically enriched ester 46. In thesecases, the product mixture can be further purified by silica gelchromatography to obtain desired products with diaseteromeric excessof >97%. The tert-butyl sulfinyl group of 46 is removed using acids suchas HCl and TFA in a suitable solvent such as MeOH or dioxane to generateamino ester 47. Other conditions to remove the t-butylsulfinyl group maybe employed as determined by those skilled in the art. β-Amino ketone 47is acylated with carboxylic acid 8 using conditions described in Scheme2 to give the β-keto amide 48. Stirring β-keto amide 48 with a base suchas sodium ethoxide in a suitable solvent such as ethanol at roomtemperature to 80° C. provides cyclic enol 49. Other conditions can alsoby used to effect the cyclization as determined by those skilled in theart. Compound 49, when treated with stoichiometric amount of achlorinating agent, such as POCl₃, at elevated temperature in an inertsolvent such as toluene, is converted to mono-chloride 50. Chloride 50can then react with various boronic reagents through a Suzuki-type ofcross coupling reaction to generate compounds of Formula (II). Thechoices of boronic reagents, catalysts, ligands, bases, solvents andtemperatures are well documented in the literature and can be selectedappropriately by those skilled in the art.

Compounds of Formula (II), where R³═R⁴═H and R¹═CONHC₄₋₁₈ alkyl orCONH(CH₂)₁₋₈Ph can be made according to Scheme 14. The phosphorous ylide5 is heated, using microwave irradiation, to 150° C. with α-ketoester 52in a suitable solvent such as THF or DMSO to give α,β-unsat'd ketone 53.α,β-Unsat'd ketone 53 is treated with concentrated aq NH₄OH in a solventsuch as DMSO in a sealed vessel to provide amine 54. Alternatively,alkene 53 may be treated with NH₃ in a solvent such as DMSO or DMSO andmethanol in a sealed vessel to provide amine 54 Amine 54 is couple withcarboxylic acid 8 using a variety of amide bond forming reactions. Forexample, carboxylic acid 8 may be converted to the corresponding acidchloride using oxalyl chloride in a solvent such as CH₂Cl₂ and catalyticDMF. Alternatively, the carboxylic acid 8 may be activated using1-chloro-N,N,2-trimethylprop-en-1-amine in a suitable solvent such asCH₂Cl₂. The acid chlorides thus formed are combined with amine 54 in asuitable solvent such as CH₂Cl₂ or CH₂Cl₂ and DMF in the presence of abase, preferably pyridine. Other amide bond forming reaction known tothose skilled in the art may be employed. Cyclization of amide 55 andsubsequent hydrolysis to a the carboxylic acid 56 typically occurs bystirring amide 55 in the presence of a weak base such as piperidine in asuitable solvent such as EtOH at a temperature between room temperatureand reflux or a base such as lithium hydroxide in a suitable solventsuch as THF and water at room temperature. Alternatively, when R⁶ is anitrile, cyclization of amide 55 typically occurs by stirring amide 55in the presence of a base such as lithium hydroxide in a suitablesolvent such as THF and water at room temperature. Hydrolysis is thencarried out under acidic conditions using a strong acid such as HCl in asuitable solvent such as acetic acid at temperatures between roomtemperature and 50° C. Carboxylic acid 56 and an amine are coupledtogether using standard amide bond forming conditions. For example,treatment of carboxylic acid 56 and an amine with HOBt, EDC and DIEA inthe presence of pyridine in a suitable solvent such as DCM at roomtemperature provides compounds having Formula (II). Other amide bondforming reaction known to those skilled in the art may be employed.

Compounds of formula 60 having R^(e)=alkyl and R⁶=cyano can besynthesized by coupling acid 56 with N,O-dimethylhydroxylamine usingtypical amide bond forming reactions. For example, carboxylic acid 56 iscoupled to N,O-dimethylhydroxylamine using EDC in the presence of base,preferably N-methylmopholine, in a suitable solvent, such as CH₂Cl₂, toprovide the Weinreb amide 57. Other amide forming reactions known tothose skilled in the art may also be employed. The intermediate Weinrebamide 57 is reacted with ethynylmagnesium bromide in an aprotic solventsuch as THF at 0-35° C. to provide the acylacetylide intermediate 58.Compounds of formula 60 are obtained when acylacetylide intermediate 58is reacted with hydrazine 59 in the presence of a base such as TEA in asuitable solvent such as EtOH.

Compounds of formula 63 having R^(b)=alkyl and R⁶=cyano can besynthesized by first coupling acid 56 with β-ketoamine 61 using typicalamide bond forming reactions. For example, carboxylic acid 56 is coupledto α-ketoamine 61 using EDC and HOBt in the presence of base, preferablyDIEA, in a suitable solvent, such as CH₂Cl₂, to provide β-ketoamide 62.Other amide forming reactions known to those skilled in the art may alsobe employed. 5-Alkyl substituted oxazole 63 is then obtained via thedehydrative cyclization of β-ketoamide 62 using a dehydrating agent,preferably POCl₃, in the presence of a suitable base, such as DIEA, in asuitable solvent such as dichloroethane at a temperature of 80-120° C.

IV. Biology

In mammals, there are two triglyceride synthesis pathways:glycerol-3-phosphate pathway and monoacylglycerol pathway. The former ismainly responsible for energy storage in the peripheral tissues such asfat, liver, skeletal muscle; the latter is essential for the dietary fatabsorption which takes place in the small intestine. When dietary fat isingested, pancreatic lipase digests triglycerides into free fatty acidsand 2-monoacylglycerol, which are absorbed by intestinal epithelialenterocytes. Once inside enterocytes, free fatty acids and2-monoacylglycerol are used as building blocks to resynthesizetriglycerides by two sequential acylation steps; first by MGAT and thenby DGAT enzyme reactions. Triglycerides are then incorporated intochylomicrons and secreted into lymph to be utilized as an energy supplyfor the body.

Monoacylglycerol acyltransferase 2 (MGAT2) is a membrane boundacyltransferase that belongs to diacylglycerol acyltransferase 2 (DGAT2)gene family. It is highly and selectively expressed in the smallintestine. Genetic deletion of MGAT2 in mice decreased the rate ofabsorption for the orally ingested triglycerides, indicating that MGAT2plays an important role for the intestinal MGAT/DGAT pathway [Yen, C. L.et al, Nat. Med., 15(4):442-446 (2009); Okawa, M. et al., Biochem.Biophys. Res. Commun., 390(3):377-381 (2009)]. When chronicallychallenged with a high fat diet, in contrast to wild type mice thatbecame obese, MGAT2 knockout mice resisted the impact of high-fatfeeding and demonstrated with a lower body weight, less adiposity, andless hepatic fat accumulation. In contrast to hyperinsulinemic wild typemice after high-fat challenge, MGAT2 deletion normalizes the insulinlevel and decreased fasting glucose. In the glucose tolerance test, theyalso had an improved glucose excursion. Consistent with their improvedglycemic profile, MGAT2 knockout mice also had an increased level ofGLP1, an incretin gut hormone that profoundly impacts glucose metabolism[Yen, C. L. et al., Nat. Med., 15(4):442-446 (2009)]. Taken together, itis expected that inhibition of MGAT2 through pharmacologicalintervention would provide the same benefit as demonstrated in theknock-out mice, e.g., resistance to weight gain, or conversely,reduction in fat body mass. In addition, MGAT2 inhibition would lead toan improved insulin sensitivity and glucose metabolism which eitherleads to a decrease in the incidence of Type II diabetes, or a treatmentof diabetic condition.

It is also desirable and preferable to find compounds with advantageousand improved characteristics compared with known anti-diabetic agents,in one or more of the following categories that are given as examples,and are not intended to be limiting: (a) pharmacokinetic properties,including oral bioavailability, half life, and clearance; (b)pharmaceutical properties; (c) dosage requirements; (d) factors thatdecrease blood drug concentration peak-to-trough characteristics; (e)factors that increase the concentration of active drug at the receptor;(f) factors that decrease the liability for clinical drug-druginteractions; (g) factors that decrease the potential for adverseside-effects, including selectivity versus other biological targets; and(h) improved therapeutic index with less propensity for hypoglycemia.

As used herein, the term “patient” encompasses all mammalian species.

As used herein, the term “subject” refers to any human or non-humanorganism that could potentially benefit from treatment with a MGAT2inhibitor. Exemplary subjects include human beings of any age with riskfactors for metabolic disease. Common risk factors include, but are notlimited to, age, sex, weight, family history, or signs of insulinresistance such as acanthosis nigricans, hypertension, dyslipidemia, orpolycystic ovary syndrome (PCOS).

As used herein, “treating” or “treatment” cover the treatment of adisease-state in a mammal, particularly in a human, and include: (a)inhibiting the disease-state, i.e., arresting it development; and/or (b)relieving the disease-state, i.e., causing regression of the diseasestate.

As used herein, “prophylaxis” or “prevention” cover the preventivetreatment of a subclinical disease-state in a mammal, particularly in ahuman, aimed at reducing the probability of the occurrence of a clinicaldisease-state. Patients are selected for preventative therapy based onfactors that are known to increase risk of suffering a clinical diseasestate compared to the general population. “Prophylaxis” therapies can bedivided into (a) primary prevention and (b) secondary prevention.Primary prevention is defined as treatment in a subject that has not yetpresented with a clinical disease state, whereas secondary prevention isdefined as preventing a second occurrence of the same or similarclinical disease state.

As used herein, “risk reduction” covers therapies that lower theincidence of development of a clinical disease state. As such, primaryand secondary prevention therapies are examples of risk reduction.

“Therapeutically effective amount” is intended to include an amount of acompound of the present invention that is effective when administeredalone or in combination to inhibit MGAT2 and/or to prevent or treat thedisorders listed herein. When applied to a combination, the term refersto combined amounts of the active ingredients that result in thepreventive or therapeutic effect, whether administered in combination,serially, or simultaneously.

A. Assay Methods MGAT SPA Assay

MGAT2 enzyme was assayed using membranes isolated from Sf9 cellsexpressing the recombinant human MGAT2 cDNA with 2-monooleoylglyceroland [³H]-oleoyl-CoA as substrates as described by Seethala et al. [Anal.Biochem., 383(2):144-150 (Dec. 15, 2008)]. Briefly, the assays wereconducted in 384-well plates in a total volume of 30 μL, at 25° C. Ineach assay, 200 ng of recombinant human MGAT2 membrane was incubatedwith 10 μM of 2-monooleoylglycerol and 15 μM of [³H]-oleoyl-CoA in 100mM potassium phosphate (pH 7.4) for 20 min with various concentrationsof compounds delivered in DMSO. The assay was terminated by the additionof 20 μl of Stopping Solution (7.5 mg/ml Yittrium Oxide Polylysinebeads, 3.3 mg/ml Fraction V BSA and 200 μM Mercuric chloride in 50 mMHEPES, pH 7.4). The signal was measured 1 h after quenching the reactionusing LEADSEEKER™ for 5 minutes. To calculate the degree of inhibition,the zero level of enzyme activity (blank) was defined by the above assayprocedure using membrane form Sf9 cell uninfected with baculovirus(Naive) and the 100% level of MGAT2 enzyme activity was defined by humanMGAT2 assay with the vehicle DMSO. The IC₅₀s of inhibitors weredetermined by logistic 4 parameter equation in XL-fit.

MGAT LCMS Assay

The MGAT enzyme reactions were performed in CORNING Falcon 96-well

Polypropylene plates, in a total volume of 60 μL, of 50 mM PotassiumPhosphate buffer pH 7.4, containing a final concentration of 100 μM2-oleoylglycerol, 15 μM oleoyl-Coenzyme A and 0.0013 μg/μL Human orMouse MGAT-2 or 0.0026 μg/μL Rat recombinant MGAT-2 membranes expressedin Sf9 cells. Assay plates were run through a fully automated roboticssystem and shaken for 5 seconds every minute for a total 10 minutes. Thereactions were then quenched with 120 μL, of ice cold methanolcontaining 1 μg/mL 1,2-distearoyl-rac-glycerol as the internal standard.Plates were shaken for 2 minutes and spun down to remove proteinprecipitation. After the spin, samples were transferred to LC/MScompatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump,utilizing a Waters Symmetry C8, 50×2.1 mm column, was used for thechromatography of enzyme products. The buffer system consists of 0.1%formic acid in water with a mobile phase consisting 0.1% formic acid inmethanol. The shallow gradient is 90-100% mobile phase in 0.2 min with atotal run time of 2.3 min. The first 0.5 minutes of each injection wasdiverted to waste to eliminate the presence of Phosphate buffer in theenzymatic reaction. The column was run at 0.6 mL/min and a temperatureof 65° C. Mass spectrometry analysis of the samples was performed on aThermoFisher Quantum Triple quad utilizing APCI (+) as the mode ofionization. Data was acquired in Single Ion Monitoring (SIM) modeanalyzing Diolein=m/z 603.6 (PRODUCT) and 1,2-distearoyl-rac-glycerol(IS)=m/z 607.6. The ratio of Diolein to internal standard (Peak AreaRatio) is utilized to calculate IC₅₀ values.

The above other therapeutic agents, when employed in combination withthe compounds of the present invention may be used, for example, inthose amounts indicated in the Physicians' Desk Reference, as in thepatents set out above, or as otherwise determined by one of ordinaryskill in the art.

Particularly when provided as a single dosage unit, the potential existsfor a chemical interaction between the combined active ingredients. Forthis reason, when the compound of the present invention and a secondtherapeutic agent are combined in a single dosage unit they areformulated such that although the active ingredients are combined in asingle dosage unit, the physical contact between the active ingredientsis minimized (that is, reduced). For example, one active ingredient maybe enteric coated. By enteric coating one of the active ingredients, itis possible not only to minimize the contact between the combined activeingredients, but also, it is possible to control the release of one ofthese components in the gastrointestinal tract such that one of thesecomponents is not released in the stomach but rather is released in theintestines. One of the active ingredients may also be coated with amaterial that affects a sustained-release throughout thegastrointestinal tract and also serves to minimize physical contactbetween the combined active ingredients. Furthermore, thesustained-released component can be additionally enteric coated suchthat the release of this component occurs only in the intestine. Stillanother approach would involve the formulation of a combination productin which the one component is coated with a sustained and/or entericrelease polymer, and the other component is also coated with a polymersuch as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) orother appropriate materials as known in the art, in order to furtherseparate the active components. The polymer coating serves to form anadditional barrier to interaction with the other component.

These as well as other ways of minimizing contact between the componentsof combination products of the present invention, whether administeredin a single dosage form or administered in separate forms but at thesame time by the same manner, will be readily apparent to those skilledin the art, once armed with the present disclosure.

The compounds of the present invention can be administered alone or incombination with one or more additional therapeutic agents. By“administered in combination” or “combination therapy” it is meant thatthe compound of the present invention and one or more additionaltherapeutic agents are administered concurrently to the mammal beingtreated. When administered in combination, each component may beadministered at the same time or sequentially in any order at differentpoints in time. Thus, each component may be administered separately butsufficiently closely in time so as to provide the desired therapeuticeffect.

The compounds of the present invention are also useful as standard orreference compounds, for example as a quality standard or control, intests or assays involving the MGAT2 enzyme. Such compounds may beprovided in a commercial kit, for example, for use in pharmaceuticalresearch involving MGAT2 or anti-diabetic activity. For example, acompound of the present invention could be used as a reference in anassay to compare its known activity to a compound with an unknownactivity. This would ensure the experimentor that the assay was beingperformed properly and provide a basis for comparison, especially if thetest compound was a derivative of the reference compound. Whendeveloping new assays or protocols, compounds according to the presentinvention could be used to test their effectiveness.

The compounds of the present invention may also be used in diagnosticassays involving MGAT2.
